IDC: China smartphone market declined 5% in 2017
Apple shipped almost 10% fewer phones in the past 12 months, compared to 2016, but it remained a leader in the premium segment with 85% of all sales over $600. Due to impressive shipments of the iPhone X (about 7 million units, according to Canalys), Cupertino actually saw an increase in its YoY and QoQ share in premium sales. The phone arrived almost a month after its closest competitor Huawei Mate 10, but that did not prevent it from outselling it.
Huawei kept its top spot on the Chinese market in 2017 mostly due to its shipments in the ultra-cheap segment - under $200. The company shipped 24.3 million Huawei and Honor branded devices in Q4, and amounted to 90.9 million units for the whole 2017.
The mid-range segment is the strength of Oppo and vivo, with both BKK subsidiaries posting an increased portfolio in this sector, but due to the saturation of the market and the reduction of shipments in the low-end spectrum, both saw a decline on a yearly basis.
Samsung once more missed on making the top spots in China Samsung. IDC reports the Korean giant is still having troubles in the market, where it can't successfully compete with local makers.
